RADIUS Extensions for Port Set Configuration and Reporting
draft-cheng-behave-cgn-cfg-radius-ext-05
Abstract
This document defines new RADIUS attributes that can be used by a
device implementing port ranges to communicate with a RADIUS server
to configure and/or report TCP/UDP port sets and ICMP identifiers
mapping behavior for specific hosts. This mechanism can be used in
various deployment scenarios such as CGN, NAT64, Provider WiFi
Gateway, etc.
This document does not make any assumption about the deployment
context.
Requirements Language
